If pressure is given by P=A+B by t and -c by D +v where t and v are time and velocity respectively then find dimensional formula of A, B,C&D.

    Please write your equations in an acceptable standard way. Do not use words like "and" and "by" in the equation.

    Do you mean
    P = A + B/t - C/(D+v) ?

    What do you mean by a "dimensional formula?"

    In the equation I have written,
    A has dimensions of pressure
    B has dimensions of (pressure)*time
    C has dimensions of (pressure)/(velocity)
    D has dimensions of velocity

    yes i mean the above equation which u have written P=A+B/T-C/D+V.


    The expression which shows how and which of the base quantities represent the dimensions of a physical quantity is called the dimensional formula.

    M - mass,
    L - length,
    T - time
    Pressure P
    Pa= N/m² = kg•m/s²m²=kg/m•s² =M•L^-1•T^-2 ,
    A = M•L^-1•T^-2 ,
    B= M•L^-1•T^-1,
    C = M•L^-2•T^-1,
    D =L•T^-1.

    thank u mam.

    i have not understood how n/m square it comes kgm/s2m2 and the cap symbol.

  • physics -

    Newton is the unit of force
    F= ma =>
    m –> kg
    a-> m/s²
    N = kg•m/s² =M•L•T^-2
